[0019] Specific implementation process:

[0020] The well-produced pile of spikes is conveyed to the spike flattening mechanism 9 by the upper conveyor belt, and the conveyor belt of the spike flattening mechanism 9 moves to the right at the same speed V1 as the upper conveyor belt. When the spikes contact the spike pushing plate 10, the spike pushing cylinder 2 pushes the cylinder pushing plate 8 to the left, and the spike pushing plate 10 moves to the left, pushing the upper layer of spikes on the conveyor belt of the spike flattening mechanism 9 flat. Then the spike pushing cylinder 2 pulls the cylinder pushing plate 8 back to the right, and the spike pushing plate 10 moves to the right and returns to the initial position. At this time, the conveyor belt of the spike flattening mechanism 9 continues to move to the right at V1. When the spikes contact the spike pushing plate 10 again, the spike pushing cylinder 2 repeats the above actions until all the spikes flattened on the conveyor belt of the spike flattening mechanism 9 can pass through the spike pushing plate 10 smoothly. The spikes passing through the spike pushing plate 10 are conveyed to the first baffle 4 by the conveyor belt of the spike flattening mechanism 9. Under the combined action of the conveyor belt of the spike flattening mechanism 9 and the first baffle 4, only the lower layer of spikes can pass through the first baffle 4. When the lower layer of spikes passes through, the upper layer of spikes falls on the conveyor belt of the spike flattening mechanism 9 and continues to pass through the first baffle 4. The spikes passing through the first baffle 4 move to the right with the conveyor belt of the spike flattening mechanism 9 to the position of the second baffle 5. Under the combined action of the conveyor belt of the spike flattening mechanism 9 and the second baffle 5, only the layer of spikes close to the conveyor belt of the spike flattening mechanism 9 can pass through the second baffle 5 directly, and the remaining spikes fall on the conveyor belt of the spike flattening mechanism 9 after the lower layer of spikes passes through the second baffle 5 and pass through in turn. After passing through the above process, all the spikes are single-layered and flat on the conveyor belt of the spike flattening mechanism 9, ready for subsequent separation. The spikes passing through the second baffle 5 move at a constant speed V1 on the conveyor belt of the spike flattening mechanism 9. When the spikes are conveyed to the end of the conveyor belt, all the spikes start to move in a flat trajectory at a speed of V1, and fall on the first accelerating conveyor belt 12 moving at a constant speed V2 (V2>V1). Because there is a time difference between each spike when falling on the first accelerating conveyor belt 12, and V2>V1, the distance between adjacent two spikes is enlarged. When the spikes are conveyed to the end of the first accelerating conveyor belt 12, all the spikes start to move in a flat trajectory at a speed of V2, and fall on the first turning conveyor belt 14 turning at a speed of V2, completing the turning. When the spikes are conveyed to the end of the first turning conveyor belt 14, all the spikes start to move in a flat trajectory at a speed of V2, and fall on the second accelerating conveyor belt 15 moving at a constant speed V3 (V3>V2). Because there is a time difference between each spike when falling on the second accelerating conveyor belt 15, and V3>V2, the distance between adjacent two spikes is enlarged again.

[0021] When the spike separating mechanism 1 is working, the spike boxing mechanism 23 is also working, the full-automatic box opening machine 24 opens and forms the paper box from the prepared paper box board, and then is conveyed to the paper box conveying belt 25, under the joint action of the paper box conveying belt 25 and the paper box movement fixing belt 26, the paper box is conveyed to the position directly below the parallel robot 21, and the paper box stops running. At this time, the parallel robot 21 sucks and puts the spikes close to the parallel robot 21 on the secondary acceleration conveying belt 15 into the paper box, and when the bottom layer of the paper box is filled with 10 spikes, the tray separating and boxing mechanism 27 starts to work.

[0022] The tray pushing cylinder 28 pulls the tray cylinder pushing plate 30 back, the worker places the tray to be separated on the tray conveying belt 46, and then moves towards the tray baffle 47 under the pushing of the tray conveying belt 46 and the tray cylinder pushing plate 30, when the tray to be separated contacts the tray baffle 47, the tray pushing cylinder 28 stops pushing, at this time, the upper part of each plastic tray is pressed by a row of tray separation cards 45. At the same time, the grabbing cylinder 41 is in the initial position under the control of the program, at this time, the grabbing cylinder pushing plate 48 and the grabbing cylinder slider 43 are located at one end close to the grabbing cylinder fixed plate 40, at this time, the suction disc fixed plate 34 is pushed vertically downward under the action of the double-rod cylinder 37, when the push rod of the double-rod cylinder 37 is fully extended, the lower end of the suction disc 35 and the pressure sensor 36 just contacts the bottom end of the first plastic tray in a stack of plastic trays. At this time, the six suction discs 35 simultaneously suck, so that the bottom end of the first plastic tray is in close contact with and tightly sucked by the suction disc 35, and then the suction disc fixed plate 34 is pulled vertically upward under the action of the double-rod cylinder 37, at the same time, the surfaces of the second, third, and the like plastic trays are kept in the original position under the pressure action of the tray separation card 45, so that the first plastic tray is pulled up by the tray separation and boxing mechanism 27. Then, the grabbing cylinder 41 pushes the grabbing cylinder pushing plate 48 to move away from the grabbing cylinder fixed plate 40 until it is fully extended. Then, the suction disc fixed plate 34 is pushed vertically downward under the action of the double-rod cylinder 37, when the push rod of the double-rod cylinder 37 is fully extended, the six suction discs 35 are simultaneously released, and the plastic tray falls into the carton, completing the separation of the first plastic tray. Then, the parallel robot 21 sucks and puts the spikes close to the parallel robot 21 located on the secondary acceleration conveying belt 15 into the carton, when the bottom layer of the spikes in the carton is placed for 10, the tray separation and boxing mechanism 27 starts to work, the suction disc fixed plate 34 is pushed vertically downward under the action of the double-rod cylinder 37, when the push rod of the double-rod cylinder 37 is fully extended, the lower end of the suction disc 35 and the pressure sensor 36 is a certain distance away from the second plastic tray, at this time, the screw module 38 pushes the double-rod cylinder 37 to move downward, when the lower end of the pressure sensor 36 contacts the bottom end of the second tray, the process of the first grabbing is repeated. The cycle continues until 50 spikes are filled, and then the carton is conveyed to the next level mechanism under the joint action of the carton conveying belt 25 and the carton movement fixed belt 26. The spike separation mechanism 1, the spike boxing mechanism 23 and the tray separation and boxing mechanism 27 continue to repeat the above operation. The spikes not grabbed by the parallel robot 21 continue to return to the primary acceleration conveying belt 12 under the comprehensive action of the climbing conveying belt 19, the secondary turning conveying belt 17, the spike backflow conveying belt 18, the second spike baffle 13 and the third spike baffle 16, and wait for the next separation and grabbing.

Any equivalent changes and improvements made according to the scope of the application should still belong to the patent coverage of the application.
